If your goal is to win the ar­gu­ment, then you’re mak­ing the mis­take of let­ting the other guys frame the dis­cus­sion. What ev­i­dence do they have for any of this mir­a­cle stuff?

I’m con­fused by your com­ment. The main re­mark Mar­ius was mak­ing was that he found one skep­ti­cal claim (that which he at­tributes to “Re­form Rab­bis”) as not likely. I don’t see how that con­nects with your re­mark which seems to only make sense if Mar­ius had been ar­gu­ing with re­li­gious in­di­vi­d­u­als who were us­ing the claimed mir­a­cle of Chanukah as ev­i­dence for their re­li­gion.
